Overview
This chapter introduces Rockwell Automation’s Bulletin 2364F
synchronous line, regenerative DC bus supply unit (RGU).
What is the 2364F? The RGU is designed to be the regenerative front-end of a common
DC bus drive system. RGUs are available with 380V, 460V, and
575V 3-phase input voltages. Read this section for a general
description of RGU functionality and packaging.
What does the RGU do?
Your RGU facilitates bi-directional power flow between the 3-phase
AC input and the common DC bus:
• The RGU converts the incoming 3-phase, AC line voltage into a
regulated DC bus voltage by controlling the power flow to and
from the AC line.
• The RGU converts an incoming 3-phase, AC line voltage into a
115V AC RGU control voltage via a basic capacity control
transformer (with optional increased transformer capacities
available if you desire to also supply control power to a 115V AC
control bus).
How will the RGU fit into a 2362 drive system?
The RGU is packaged in CENTERLINE™ Bulletin 2100 motor
control centers (MCC) to be compatible with 2362 common DC bus,
AC drive system lineups. As an added convenience, you can connect
other common bus MCCs to both the right and left sides of standalone
RGUs.
